“Harry’s got a record for pulling some of the most beautiful women in showbiz and couldn’t resist Lucy’s beautiful looks. He found her ­really witty and very sexy,” a source told the newspaper today.

While Lucy was married, the insider claimed that she and her husband were leading “virtually separate lives”.

The source explained: “Lucy was going through a rocky patch with her husband. After only a year of marriage she had doubts over ­whether she had done the right thing. She had requested taking time out in their relationship and they were virtually ­leading separate lives.

“Harry just happened to be in the right place at the right time. He charmed his way into her life and brought a little bit of excitement with him.

“Lucy was confused about her feelings for her husband. They were still living in the same house but not actually living as a couple.”

But with her fling with Harry lasting just weeks, Lucy was apparently left devastated about ‘cheating’ on her husband.

The source went on: “She ­wanted to make a real go of her ­marriage and decided the only way to do that was to confess about Harry. She was terrified of admitting what she had done.

“Although she believes she was ­separated from her husband at the time, she knew he would hate it. But she knew it was the only way of moving forward.

“As you can imagine it was tough. He was mad. She was mortified.

“But they are working their way through the troubles and are glad they have ­decided to stay together.”

A source “close to Harry” insisted that he was under the impression that Lucy wasn’t married.

The pal added: “To Harry it was very clear that Lucy had separated from her husband. He had no idea she was still married.”
